| IfIndex |
| The interface index of the link to be predefined. This object identifies a row in the ifTable. |
| Addr |
| On point-to-point links, this field must be empty. On point-to-multipoint links, this field may be empty or set to a partners (MAC-) address. In the first case, the definition is valid for all links on the interface except for those having a specific predefiniton. In the second case the definition defines the link parameters for a specific partner. |
| Mode |
| This field indicates, whether the link is initially operated in DTE or DCE mode. If a misconfiguration is detected, (DTE<->DTE od DCE<->DCE) the DTE/DCE assignement is done be means of the procedure defined in ISOxxxx. Enumerations: |
| Modulo |
| This object indicates, whether the link should be operated in modulo 8 or modulo 128 mode. Enumerations: |
| LIC |
| Lowest Incoming Channel as seen from the DTE. Depending on the value of x25LkPrVC0, the value of -1 or Zero means no incoming channels. Range: -1 to 4095 |
| HIC |
| Highest Incoming Channel as seen from the DTE. Depending on the value of x25LkPrVC0, the value of -1 or Zero means no incoming channels. Range: -1 to 4095 |
| LTC |
| Lowest Twoway Channel as seen from the DTE. Depending on the value of x25LkPrVC0, the value of -1 or Zero means no twoway channels. Range: -1 to 4095 |
| HTC |
| Highest Twoway Channel as seen from the DTE. Depending on the value of x25LkPrVC0, the value of -1 or Zero means no twoway channels. Range: -1 to 4095 |
| LOC |
| Lowest Outgoing Channel as seen from the DTE. Depending on the value of x25LkPrVC0, the value of -1 or Zero means no outgoing channels. Range: -1 to 4095 |
| HOC |
| Highest Outgoing Channel as seen from the DTE. Depending on the value of x25LkPrVC0, the value of -1 or Zero means no outgoing channels. Range: -1 to 4095 |
| DefPktSize |
| The Layer 3 packet size for this link. Enumerations: - p128 (7)
- p256 (8)
- p512 (9)
- p1024 (10)
- p2048 (11)
- p4096 (12)
|
| DefWinSize |
| The default window size. This must be less than 8, if the layer 3 is operated in modulo 8 mode. Range: 1 to 127 |
| MaxPktSize |
| The maximum allowable packet size for this link during X.25 packet size negotiation. If this field is set to unrestricted, the packet size will only be limited by the Mtu size of the interface, which is always the upper bound for the packet size. Enumerations: - unrestricted (1)
- p128 (7)
- p256 (8)
- p512 (9)
- p1024 (10)
- p2048 (11)
- p4096 (12)
|
| MaxWinSize |
| The maximum allowable window size for this link during window size negotiation. Range: 1 to 127 |
| L2WinSize |
| The layer 2 window size for this link. Range: 1 to 127 |
| L2RetrTimer |
| The retransmission timeout in milliseconds for the layer 2 of this link. If a frame is not acknowledged within this timeout, it will be retransmitted. Range: 100 to 30000 |
| L2RetrCounter |
| The retransmission counter for the layer 2 of this link. If a frame has been retransmitted more often than indicated by this object, the link will be reset or disconnected. Range: 1 to 127 |
| L2SupervTimer |
| The link-supervision timeout in milliseconds for the layer 2 of this link. This timer is started, when the link gets idle. An RR poll-sequence will be initiated, when this timeout expires. Range: 100 to 30000 |
| L2IdleTimer |
| The idle timer in milliseconds for the layer 2 of this link. If no VCs are established and the the link has been idle for the time specified by this object, the link will be disconnected. The value 0 means, the link should not be disconnected after the last VC has been cleared. A value of -1 means, that the link shall be kept up even if it get disconnected from the partner on the other end. Range: -1 to 30000 |
| Negotiation |
| This object determines whether packet-size and windows-size parameters are negotiated for outgoing calls. When set to never, outgoing calls are cleared if the call parameters differ from the default-settings. When set to when-necessary, negotiation is only performed if the call parameters differ from the default settings. When set to always, negotiation is always performed. Enumerations: - when-necessary (1)
- always (2)
- never (3)
|
| RestDelayTimer |
| The Restart delay timer in milliseconds for this link. This timer specifies the time interval between establishment of layer 2 and sending of restart packet. If layer 2 is established and the time specified by this object expired, restart packet will be sent. The value 0 means, restart packet should be sent immediately after establishment of layer 2. Range: 0 to 30000 |
| VC0 |
| This object indicates, whether VC#0 shall be allowed on the link. If this object is set to enable, VC#0 is allowed and the value -1 shall be used to indicate the absence of specified channels. This invalidates old configurations, for which a value of 0 specifies the absense of a specified channel. However, for compatibility reasons, if this object is not set to enabled, the values -1 or 0 may be used to specify the absence of a channel. Enumerations: |
| RewritingRule |
| This Object specifies a rewriting rule in the X25 Rewrite table. The call packet will be processed according to this rewriting rule before the call is being routed. If this value is set to zero, no rewriting will take place. Range: 0 to 999999 |
